Currently it is impossible to invalidate the constnat and type manager. However, the compact ids pass changes the ids for the types and constants, which makes them invalid. This change will make them analyses that have to been explicitly marked as preserved by passes. This will allow compact ids to invalidate them. Fixes #2220.
